Abstract

The Moving Least Squares(MLS) Difference Method has merits of Meshfree Method and Finite Difference Method(FDM); it provides node-based fast solution procedure. The method takes advantage of mesh independency from Meshfree Method and fast discretization of governing equations from FDM. The method is adequate for 2D transient solid problems which usually require heavy computation. Although the governing Partial Differential Equation(PDE) can be discretized in both explicit and implicit schemes, the explicit scheme can provide more efficient solution procedure compared to the implicit one. The accuracy and efficiency of the developed method are verified through numerical experiments.
